helical LSD-best oil

Recommended Posts

Im eventually removing my 2 way and putting the stock helical lsd back in.

for arguments sake.

I am getting a greddy lsd diff cover for the hell of it, but....

Before I put the assembly back together, what is the best oil to use for good reliable LSD action??

The oil won't affect the way tge helical works I don't think. Doesn't have to be LSD oil

Same oil as what u put in your gearbox from what iv been told. Maybe bit thicker. Redline heavyweight?

LSD oils have special additives for friction components, A Helical diff has only gears so you really shouldn't need any special LSD oil. Just a good heavyweight gear oil (not manual gearbox oil, many of them are too thin for differentials)

 

Your owners manual should specify a particular grade.

Wouldn't bother with the GReddy LSD cover for the Helical. They are made for clutch-type diffs which get very hot. The Helical runs no where near as hot.

Actually Greddy LSD cover cannot harm it can only do good for any diff. Cooler oil, more capacity. Just like a gearbox can get too hot so can a diff

Running motul gear 300 in my S15 helical diff for a while no problems. As the workshop manual states "do not use lsd exclusive oil use standard diff oil".

Have you seen the price of those covers though? If you really want a better rear diff cover, track down a NA Z32 or GTR rear cover and spend the ~$500 you save on something else.

Just be done with it and get Redline 75W-90NS (NS is for Non Slippery) and it lasts a long time too. I'm using it and it's responsive and doesn't make any strange creaks or knocks at all, it purrs.

 

Order it from http://www.performancelub.com, cheapest place you'll find it and they deliver to your door.

Sorry to bump this thread up...

But is anyone using Redline Lightweight in the Helical Diff (S15)?

I've got someone lying around and just wanted to change the diff oil.....
